Résumé

OBJECTIVE:To optimize the extraction technology of Baiyi rectal solution. METHODS:The effects of water amount and extraction time on extraction technology were investigated by central composite design-response surface method using OD value of berberine hydrochloride and ferulic acid and the extract yield as index. Validation test was also conducted. RESULTS:The optimal extraction technology was as 11-fold water,decocting 70 min for the first time;5-fold water,decocting 30 min for the second time. In validation test,OD value of first extraction was 0.940 0,and the bias between observed and predicted values was -2.07%;that of second extraction was 0.851 8,and the bias was -2.41%. CONCLUSIONS:The extraction technology of Baiyi rectal solution is reasonable,feasible and suitable for industrial production.
